We look at the division of 70295371 by 321 
The aim is to understand the frequency of 321 in 70295371.

Going ahead to step 1:
When dividing 7 by 321, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 321

Going ahead to step 2:
321 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Fetch the next digit (2) from the dividend, attach it to 70 and continue: 702 / 321

Advancing to step 3:
When dividing 702 by 321, we get 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 642 from 702 and we're left with 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 321

Going ahead to step 4:
The number 321 fits into 609 1 times, leaving a remainder of 288.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 321 from 609 leaves us with 288.
Append the next digit (5) from the dividend to 288 and continue with: 2885 / 321

Advancing to step 5:
If we divide 2885 by 321, we get 8 and a remainder of 317.
The next digit of our result is 8. 
Result so far: 218.0
Subtracting 2568 from 2885 leaves us with 317.
Append the next digit (3) from the dividend to 317 and continue with: 3173 / 321

Going ahead to step 6:
The number 321 fits into 3173 9 times, leaving a remainder of 284.
Write down 9 as next digit of the result. 
Result so far: 2189.0
Subtracting 2889 from 3173 leaves us with 284.
Append the next digit (7) from the dividend to 284 and continue with: 2847 / 321

Going ahead to step 7:
If we divide 2847 by 321, we get 8 and a remainder of 279.
The number 8 becomes the next digit in our result. 
Result so far: 21898.0
The remainder is 279 after subtracting 2568 from 2847.
Fetch the next digit (1) from the dividend, attach it to 279 and continue: 2791 / 321

Step 8:
321 can be fit into 2791 8 times, resulting in a remainder of 223.
The next digit of our result is 8. 
Result so far: 218988.0
If we take 2568 away from 2791, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 9:
When dividing 2230 by 321, we get 6 with a remainder of 304.
Use 6 as the next digit of our solution. 
Result so far: 218988.6
If we subtract 1926 from 2230, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 10:
The number 321 fits into 3040 9 times, leaving a remainder of 151.
Put 9 as the next digit of the answer. 
Result so far: 218988.69
The remainder is 151 after subtracting 2889 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 11:
1510 divided by 321 is 4 with a remainder of 226.
Use 4 as the next digit of our solution. 
Result so far: 218988.694
Subtracting 1284 from 1510 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 12:
When dividing 2260 by 321, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 218988.6947
The remainder is 13 after subtracting 2247 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 13:
The number 321 fits into 130 0 times, leaving a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 218988.6947
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 14:
If we divide 1300 by 321, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 218988.694704
The remainder is 16 after subtracting 1284 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 15:
The number 321 fits into 160 0 times, leaving a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 218988.694704
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 16:
321 can be fit into 1600 4 times, resulting in a remainder of 316.
Record the quotient 4 as the next digit in the result. 
Result so far: 218988.69470404
Subtract 1284 from 1600 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

The quotient of the division is 218988.69470404, and the remainder is 3.16e-07.
